I have had a few people ask for this now, so i'll consider adding support for it at somepoint.can you make an option/feature to copy hakate payload as payload.bin to the root of sd card ? Some rcm injector (like r4s dongle) use that payload.bin
For now, you can use this https://github.com/ITotalJustice/PayloaderNX/releases (fork of payload_launcher) which is basically a payload manager, and can do what you asked (and a few other cool things).
It's a bit old, and I had only just started learning to code then, so if you like the app, I can cam re-write it with a nice gui and a few more payload features. Hope that helps!
